WELL-DRIVING POINT.

Specification of Letters Patent.

Application filed June 18, 1909.

Patented Sept. 26, 1911. Serial No. 502,977.

Tooll whom it may concern:

Be it known that I, JACOB H. BERKY, a citizen of the United States,residing at- River Park, in the county of St. Joseph and State ofIndiana, have invented certain new and useful Improvements inWell-Driving Points, of which the following is a specification.

This invention relates to well driving points.

In the well-driving points now in common use, wherein there is providedan outer perforated tube, it frequently happens that when the water doesnot reach above the uppermost perforations, that air is sucked into suchupper perforations, and in commingling with the water interferes withproper operation of the pump. The ordlnary point is usually aboutthirty-six nches long, and it frequently happens that in dry weatherthere will not be a sufiicient head of water to cover all of theperforations in the point, and in operation air will enter some of theperforations and mix with the water, resulting in a scanty supply ofwater to be raised.

It is therefore one object of my invention to provide a well drivingpoint embodying such characteristics that it will operate effectually inshallow water in direct contradistinction to similar devices, such asthose hereinbefore outlined, and one wherein there will be an adequatesupply of water raised irrespective of whether the device is completelysubmerged in the water.

Another object of the invention is to provide a well driving pointembodying considerable rigidity between the tube proper and its extremepoint to prevent the point from buckling when contacting with hardsurfaces or gravel during the driving of the well.

With the above and other objects in View, the present invention consistsin the combination and arran ement of parts hereinafter more fullydescribed, illustrated in the accompanying drawings, and particularlypointed out in the appended claim, it being understood that changes maybe made in the form, proportion, size and minor details withoutdeparting from the spirit or sacrificing any of the advantages of theinvention.

In the drawings, Figure 1 is a vertical sectional view of my well point.Fig. 2 is a transverse sectional view on the line a:-w of Fig. 1. Fig. 3is a transverse sectional view on the line g 1 of Fig. 2.

Referring now more particularly to the accompanying drawings, thereference character 1 indicates a tapering driving point, whose head isprovided in its upper face with a circular groove 2 adapted to receivethe outer and inner tubings 4: and 5, respectively, the outer tubingbeing perforated throughout its length, as indicated at 6, and screwthreaded at its inner end for screw threaded engagement with thecoupling 7 to which latter another section 8 of the tubing is screwthreaded, as clearly shown in Fig. 1. The coupling 7 is provided with aninternal annular rib, whose opposite sides form shoulders for theseating of the tube at and section 8, and whose inner periphery is screwthreaded for screw threaded engagement with the inner tubing 5, andwhich, with the circular projection 3 insures a proper centering of thetube 5 with respect to the outer tube 4, the outer tubing having ascreen or other foraminous material 9 surrounding it to serve as ashield to afford an effectual exclusion of sand, so that the sand cannotenter the tubing through its perforations and choke up the water passageor in any way obstruct or interfere with a proper operation of thedevice.

If the inner tube 5 should be eliminated from the structure and thedevice should be put into operation and the water head did not reach theuppermost perforations, there would be a consequent suction of air intothe uppermost perforations which would interfere with an efficientoperation of the device. It is for this reason that I provide the innertubing 5 which it will be noticed is not perforated throughout itslength as is the case with the outer tubing, the inner tubing beingprovided with openings 10, preferably elongated and disposed at thelower end of the inner tube only. Thus in the event that air shouldenter the uppermost perforations of the outer tubin as indicated byarrows in Fig. 1, it coul not enter the inner tubing since theperforations at the bottom of the latter are submerged in or sealed bythe water. It will thus be seen that by having the perforations at thebottom of this inner tube very shallow strata of water can besufficiently raised by a suitable pump attached to the tubing.

By virtue of the peculiar connection or mounting of thetubes in the head1 of the drill point, there is provided a firm connection between thepoint and tubings and one which Will prevent buckling of the point inthe event of operation of the device on hard surfaces or upon gravel.

What is claimed is A device of the character described comprising a headhaving an annular groove in its inner end, a perforated tube having oneend secured in said groove against the outer wall of the latter, and aninner tube spaced from the outer tube and having one end 1 securedagainst the inner Wall of said groove,

the space between the tubes being unrestrict- 15 ed and the inner tubehaving unrestricted, narrow, comparatively velongated openings at itsouter end and disposed longitudinally of the tube and in spaced relationto said head, the remaining portion of the inner tube be- 20 ingimperforate, and wire gauze embracing the outer surface of the outertube. In testimony whereof I aflix my signature,

in presence of two witnesses.
